Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial crops in the Amaryllidaceae (amaryllis) family. Various common labels including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by way of a cup- or trumpet-shaped corona. The flowers are generally white or yellow (orange or pink in garden types), with either uniform or contrasting coloured tepals and corona.
Narcissus were well known in ancient civilisation, both medicinally and botanically, but formally defined by Linnaeus in his Varieties Plantarum (1753). The genus is normally thought to have about ten parts with about 50 species. The amount of types has mixed, depending on how they are grouped, a consequence of to similarity between hybridization and species. The genus arose a while in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent regions of southwest Europe. The precise source of the name Narcissus is anonymous, but it is linked to a Greek term for intoxicated (narcotic) and the misconception of the young ones of this name who fell in love with his own representation. The English expression 'daffodil' is apparently produced from "asphodel", with which it was compared commonly.
The species are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the European Mediterranean, particularly the Iberian peninsula. Both wild and cultivated plants have naturalised widely, and were created into the Far East to the tenth hundred years prior. Narcissi tend to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, diseases and disorders include viruses, fungi, the larvae of flies, mites and nematodes. Some Narcissus species have grown to be extinct, while some are threatened by increasing urbanisation and tourism.
Historical accounts suggest narcissi have been cultivated from the initial times, but became increasingly popular in Europe after the 16th century and by the late 19th century were an important commercial crop centred mainly on the Netherlands. Today narcissi are popular as lower bouquets and as ornamental plant life in private and open public gardens. The long history of breeding has led to thousands of different cultivars. For horticultural purposes, narcissi are labeled into divisions, covering an array of colours and shapes. Like other members of these family, narcissi create a number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal utilization in traditional healing and has resulted in the production of galantamine for the treating Alzheimer's dementia. Long celebrated in art work and literature, narcissi are associated with a number of themes in different cultures, ranging from death to fortune, and as icons of springtime. The daffodil is the national bloom of Wales and the image of malignancy charities in many countries. The appearance of the crazy flowers in planting season is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering to the underground storage bulb. They regrow in the following 12 months from brown-skinned ovoid light bulbs with pronounced necks, and reach heights of 5-80 cm depending on the species. Dwarf species such as N. asturiensis have a maximum elevation of 5-8 cm, while Narcissus tazetta may expand as large as 80 cm.
The plant life are scapose, having a single central leafless hollow flower stem (scape). Several green or blue-green, thin, strap-shaped leaves happen from the bulb. The herb stem bears a solitary blossom, but sometimes a cluster of blooms (umbel). The blooms, that happen to be conspicuous and white or yellow usually, both or hardly ever inexperienced sometimes, consist of a perianth of three parts. Closest to the stem (proximal) is a floral pipe above the ovary, then an exterior ring made up of six tepals (undifferentiated sepals and petals), and a central disk to conical molded corona. The blooms may hang down (pendent), or be erect. A couple of six pollen bearing stamens surrounding a central style. The ovary is poor (below the floral parts) comprising three chambers (trilocular). The fruit includes a dried up capsule that splits (dehisces) launching numerous black seed products.
The bulb lays dormant following the leaves and blossom stem die back and has contractile roots that draw it down further into the soil. The blossom leaves and stem form in the light bulb, to emerge the following season. Most varieties are dormant from summer time to late winter, flowering in the springtime, though a few species are fall flowering.
